automation platform
Modbus Plus
The application program allows event-initiated communications and incorporates
network diagnostics using either instructions in MSTR 984LL language or an
equivalent function in an IEC 1131 language. A central computer can implement the
Modbus Plus protocol, with NetBios-compatible software libraries that are called by
this computer's application program. Appropriate libraries are provided for each type
of computer interface, for the majority of platforms and operating systems.
Modbus Plus is a stand-alone network that uses inexpensive twisted-pair cables. It is
a “plug and play” network. Modbus Plus connectivity is available on a great variety of
PLC families, with additional connectivity made possible through our Collaborative
Automation partnership program. Modbus Plus supports up to 20,000 registers per
second in a predictable, deterministic manner. Modbus Plus functionalities are
based on a global database and a data table exchange mechanism.
Diagnostic programs and visual LED indicators are an aid to network operation.
For high-availability applications, Schneider Automation offers a series of
Modbus Plus network components and options for redundant operations. The
redundant cabling enables Modbus Plus communication over two independent
cable systems, with link health being checked and validated on every message
transfer. A defective link is identified in the network statistics. If one link becomes
inoperative, for any reason whatsoever, the system will automatically switch to the
other cable while the inoperative link is repaired.
